Package: postfix-policyd-spf-perl
Version: 2.005-1
Severity: important

Mail which is received at a primary MX, (which is running
postfix-policyd-spf-perl) and has transited through either a backup MX
or a non-SRS forwarder will be incorrectly marked an spf violation (hard,
or soft) by postfix-policyd-spf-perl.

There should be a way to automatically whitelist backup MX hosts, with
an additional mechanism to whitelist other hostnames, or IP addresses
(such as forwarders, or secondary IP addresses of MX hosts - in the case
where the backup MX is multi-homed, or where mail stored-and-forwarded
by a backup MX otherwise is submitted from a different IP to the
published A record of the backup MX).

A workaround is to list the IP addresses of such machines in the postfix
"mynetworks" configuration parameter, but this workaround turns the
primary MX into a willing relay for the backup MXes, or forwarders
(probably not a serious problem, but still undesirable).  It is also
brittle, as the IP address of a backup MX may legitimately be changed
without the administrator of the primary MX being notified.

Thanks!

Tim.
